I have 30 single fireformed Lapua 6mm Creedmoor cases. I'm in the process of giving them a second light forming. So I want to have a tight chamber but it seems to be mighty loose. I sized the cases with a Redding type S Match die set using the Redding competition shell holders. They allow me to start .010 backed off of the shoulder. The bolt was loose before and after sizing. There was no sign of the shoulder being touched. Bolt closes with no resistance. Using the 0.010 shell holder I was expecting that the bolt would not accept the case. Although the cases were fired for the first time in the same Savage.
Is this a case of a oversize chamber?
